Description

Technical Field

[0001] The present invention relates to the technical field of a pole double-lane safety device with intelligent reminder, and more specifically, to a pole double-lane safety device with intelligent reminder and a control method thereof. Background Art

[0002] Safety protection facilities are various facilities, equipment and tools set up at construction sites to prevent casualties during construction. For example, steel pipe columns need to be installed, adjusted, welded and tested, and all of the above work is done at high altitudes. A safe operation platform needs to be set up for high-altitude operations to change the construction safety environment and fully consider the construction characteristics of super-high-rise or large-span venues. During the construction of super-high-rise or large-span venues, steel pipe column construction is more common, and the protective measure used at this time is the operation platform.

[0003] The operating platform is a temporary side operating platform for connecting components during steel structure construction. The operating platform must be designed and calculated, approved, erected, inspected, and signed for, and its strength and stability must meet the design requirements.

[0004] In the prior art, the operating platform is built based on the materials on site. Since the structure of the operating platform is simple, the operating platform provides limited protection for the on-site workers and it is difficult to monitor the use of the wire rope. Summary of the invention

[0005] The purpose of the present invention is to provide a double-track safety device for a pole with intelligent reminder and a control method thereof, which can greatly improve the device's resistance to impact force and can have a real-time monitoring effect and a warning effect on the use status of the wire rope.

[0006] The above technical objectives of the present invention are achieved through the following technical solutions: a pole double-track safety device with intelligent reminder and a control method thereof, comprising two poles arranged at intervals, the upper ends of the two poles are respectively provided with tie pieces, the ends of the two tie pieces away from the poles are respectively provided with basket bolts, and a steel wire rope is tensioned between the two basket bolts;

[0007] The supporting structure includes a base, two vertical poles are spaced apart and rotatably arranged on the upper end surface of the base, and a guide rail is also arranged on the upper end surface of the base, the guide rail is located between the two vertical poles, and the guide rail is coplanar with the rotation plane of the two vertical poles;

[0008] The buffer structure includes a slider, a pair of sliders are symmetrically and slidably arranged on the guide rail, an elastic connecting piece is arranged between the two sliders, and connecting rods are rotatably arranged on the upper end surfaces of the two sliders, the two connecting rods are tilted upward and in a direction away from each other, and the ends of the two connecting rods away from the sliders are rotatably arranged on the sides of the two vertical rods facing each other;

[0009] The locking structure is arranged at the connection between the vertical pole and the base, or at the connection between the vertical pole and the connecting rod, or at the connection between the slider and the guide rail in a non-load-bearing state;

[0010] The control module includes a control module and a tension detection module, a signal receiving module and an alarm module which are respectively connected to the control module for communication. The tension detection module is a tension meter which is arranged on the wire rope. The tension detection module is used to detect the magnitude of the tension applied to the wire rope. The signal receiving module is arranged in the locking structure. The control module sends a corresponding unlocking control signal or locking control signal to the signal receiving module according to the force measurement signal of the tension detection module. The signal receiving module controls the locking structure to be locked or unlocked according to the corresponding signal received.

[0011] By adopting the above technical solution:

[0012] The vertical pole and the base are connected by rotation, so that the vertical pole can rotate on the base. Compared with the traditional vertical pole double-track safety device, when the wire rope has excessive tension changes, the vertical pole can rotate in opposite directions to extend the force action time to achieve the buffering function, ensuring that the wire rope will not break due to instantaneous excessive tension and bearing capacity, thereby improving the overall safety of the vertical pole double-track safety device;

[0013] The double-track safety device for the vertical poles prevents safety problems caused by excessive instantaneous rotation of the two vertical poles when they rotate toward each other due to excessive changes in the wire rope tension by setting guide rails, sliders, elastic connectors and connecting rods, and can make the process of the two vertical poles rotating toward each other smoother.

[0014] The locking structure is arranged at the connection between the vertical pole and the base, or at the connection between the vertical pole and the connecting rod, or at the connection between the slider and the guide rail in a non-load-bearing state;

[0015] The tension change on the wire rope is detected by a tension meter installed on the wire rope. The tension meter sends the data detected from the wire rope to the control module. The control module sends a corresponding unlocking or locking control signal to the locking structure according to the force measurement signal of the tension meter. The control module is also communicated with the alarm module.

[0016] The present invention is further configured as follows: the locking structure includes at least one pair of latching members and at least one pair of supporting members;

[0017] The support member is in a U shape, a connection hole is provided on one side of the support member, the support member is provided at the connection between the vertical pole and the base, or at the connection between the vertical pole and the connection rod, and one end of the support member away from the closure is symmetrically provided at both sides of the connection between the vertical pole and the base, or one end of the support member away from the closure is symmetrically provided at both sides of the connection between the vertical pole and the connection rod;

[0019] When the control module transmits a locking control signal to the signal receiving module, when the locking member is extended to the longest position, the end of the locking member away from the non-extendable member is connected to the connection hole provided on the support member and locked;

[0020] When the control module transmits the unlocking control signal to the signal receiving module, the locking member contracts to the shortest, and the end of the locking member away from the non-retractable end is disconnected from the supporting member.

[0021] By adopting the above technical solution, it is possible to lock the vertical pole when the vertical pole rotates, and to lock the vertical pole when the vertical pole does not rotate, so as to prevent the vertical pole from rotating.

[0022] The present invention is further configured as follows: the locking structure includes at least one pair of brakes, and the brakes are arranged at the connection between the vertical pole and the base or at the connection between the vertical pole and the connecting rod;

[0023] The brake comprises brake calipers symmetrically arranged on both sides of the rotation plane of the vertical pole, and the brake calipers are arranged at the connection between the vertical pole and the base or at the connection between the vertical pole and the connecting rod, and brake pads are arranged on the brake calipers.

[0024] By adopting the above technical solution, it is possible to lock the vertical pole when the vertical pole rotates, and to lock the vertical pole when the vertical pole does not rotate, so as to prevent the vertical pole from rotating.

[0025] The present invention is further configured as follows: a pin hole is arranged on the slider, a pin shaft is arranged on the guide rail and the pin shaft is a telescopic structure, and the pin hole arranged on the slider and the pin shaft are adapted to each other.

[0026] By adopting the above technical solution, the double-track safety device of the vertical pole can lock the slider in a non-load-bearing state.

[0027] The present invention is further configured as follows: the locking structure further includes a limiting structure, and the limiting structure includes:

[0028] A pair of limit blocks symmetrically arranged on the upper end surface of the base and located between the slider and the adjacent vertical rod, wherein the surfaces of the two sliders separated from each other in a non-load-bearing state are respectively in contact with the two limit blocks;

[0029] Or a pair of anti-rotation blocks are symmetrically arranged on the side surfaces of the two vertical poles that are separated from each other, and the side surfaces of the two vertical poles that are separated from each other in a non-load-bearing state are respectively in contact with the two anti-rotation blocks.

[0030] By adopting the above technical solution, it is possible to prevent the pole from generating excessive impact during the rebound process, causing the pole to tilt backward, thereby causing the wire rope to cause secondary injuries to the workers and directly break the wire rope during the subsequent rebound.

[0031] The present invention is further configured as follows: the elastic connecting member is a plurality of springs, and the elastic coefficient of a single spring is 1400N / m to 24000N / m.

[0033] The present invention is further configured such that the angle between the connecting rod and the vertical rod is 50° to 70°.

[0034] By adopting the above technical solution, the impact force of the vertical pole can be reduced.

[0035] A control method for a pole-mounted dual-lane safety device with intelligent reminder, which is applied to any of the above-mentioned pole-mounted dual-lane safety devices with intelligent reminder, comprises the following steps:

[0036] S1. The tension meter obtains the tension of the wire rope or the tension change and records it as force information and sends it to the control module;

[0037] S2. There are four thresholds in the control module, namely, over-load state, load-bearing state, under-load state and no-load state. The control module receives force information, and sends corresponding control signals to the alarm module and the locking structure according to the force information. The locking structure controls the unlocking or locking of the pole according to the control signal, and the alarm module determines whether to send an alarm signal according to the control signal.

[0038] By adopting the above technical solution, the tension meter can detect the wire rope. The tension meter sends the detected tension value to the control module, and the control module determines whether the pole needs to be unlocked or locked. The control module sends a signal to the alarm module and the locking structure.

[0039] The present invention is further configured to define the maximum bearing tension of the steel wire rope as T max , define the current tension of the wire rope as T 0 , and define when T 0 ≥85%T max It is in overload state, when 85%T max >T 0 >20%T max When it is load-bearing state, 20%T max ≥T 0 ≥5%T max It is in low load-bearing state when T 0 <5%T max S2 is in a non-load-bearing state; S2 specifically includes the following steps:

[0040] S201. When T 0 ≥85%T max When the state is 1, the locking structure is unlocked, and the alarm module sends an alarm signal;

[0041] S202. When 85% T max >T 0 >20%T max It is state 2, the locking structure is locked;

[0042] S203. When 20%T max ≥T 0 ≥5%T max It is state three, and the locking structure is locked;

[0043] S204. When T 0 <5%T max It is state 4, and the locking structure is locked.

[0044] By adopting the above technical solution, it is possible to determine whether the upright pole is unlocked or locked.

DETAILED DESCRIPTION

[0057] The following is combined with Figure 1-10 The present invention is described in further detail.

[0058] Example

[0059] like Figure 1-10 As shown, a double-track safety device for a pole with an intelligent reminder includes two poles 11 arranged at intervals, and the upper end surfaces of the two poles 11 are respectively provided with anchors 134, and the ends of the two anchors 134 away from the poles 11 are respectively provided with basket bolts 133, and the basket bolts 133 are located between the two anchors 134. A steel wire rope 131 is tensioned between the two basket bolts 133, and a rope clamp 132 is installed at the connection between the steel wire rope 131 and the basket bolt 133 to prevent the steel wire rope 131 from loosening or sliding at the connection between the steel wire rope 131 and the basket bolt 133 during operation.

[0060] As a preferred embodiment, in order to save materials while ensuring a certain tensile strength, the vertical pole 11 is a hollow steel pipe with a specification of Φ48×3.5mm.

[0061] It also includes a supporting structure 1, a buffer structure 2, a locking structure 3 and a control module.

[0062] In the prior art, the pole 11 and the base 12 of the double-track safety device for the pole are installed in a fixed connection. However, when the tension applied to the pole 11 is too large, it is easy to cause the pole 11 to bend or the connection between the pole 11 and the base 12 to break. The support structure 1 includes the base 12, and the two poles 11 are spaced and rotatably arranged on the upper end surface of the base 12. When the wire rope 131 receives tension, the force is transmitted to the buffer structure 2 to prevent the pole 11 from being bent or the connection between the pole 11 and the base 12 from being broken when the tension applied to the pole 11 is too large.

[0063] Preferably, in order to save materials while ensuring a certain tensile strength, the diameter of the steel wire rope 131 is 9 mm.

[0064] In order to prevent excessive impact force and excessive rotation of the upright pole 11, which may cause the on-site workers to directly contact the base 12 and cause unnecessary damage, the height of the wire rope 131 from the base 12 is set to 1400mm-1150mm.

[0065] As a preference, in order to prevent the workers from coming into contact with the base 12 , the height of the wire rope 131 from the base 12 is set to 1200 mm.

[0066] In the prior art, the double-track safety device for the vertical pole is not provided with a buffer area. When the device is subjected to impact force, it can only use the characteristics of the material itself to cope with it, which causes the vertical pole 11 to be easily bent or the connection between the vertical pole 11 and the base 12 to be easily broken or directly causes the wire rope 131 to be broken when the device is subjected to a large impact force. The buffer structure 2 includes a slider 21, a pair of sliders 21 are symmetrically and slidably arranged on the guide rail 121, an elastic connecting member 22 is arranged between the two sliders 21, and the upper end surfaces of the two sliders 21 are respectively rotatably provided with connecting rods 23, the two connecting rods 23 are tilted upward and in a direction away from each other, and the ends of the two connecting rods 23 away from the sliders 21 are respectively rotatably arranged on the two vertical poles 11, and the guide rail 121 is coplanar with the rotation plane of the two vertical poles 11, so that the buffer structure 2 provided in the double-track safety device for the vertical pole forms an interactive buffer area through the connection relationship between the parts, plays a role of mutual coordination, avoids the double-track safety device for the vertical pole from being subjected to impact force through the characteristics of a single part itself, and at the same time, improves the bearing capacity of the double-track safety device for the vertical pole to impact force.

[0067] In order to prevent the elastic connector 22 from being deformed or insufficiently reducing the weight due to excessive impact, the elastic connector 22 is composed of a plurality of springs 221, and the elastic coefficient of a single spring 221 is 1400N / m~24000N / m;

[0068] When the elastic coefficient of the spring 221 is less than 1400 N / m, it is easy to produce permanent bending upward or left and right when subjected to an impact force, and the spring 221 may even pop out directly to injure someone, thereby causing the spring 221 to be directly scrapped;

[0069] When the elastic coefficient of the spring 221 is greater than 24000 N / m, the stress of the spring 221 is too large, and the mitigation of the impact force is limited, which easily causes the stress of the spring 221 to be too large, thereby failing to achieve the buffering effect.

[0070] Preferably, in order to prevent excessive impact force from directly causing deformation of the elastic connector 22 or insufficient weight reduction, the elastic connector 22 is composed of nine springs 221, and the elastic coefficient of a single spring 221 is 1600N / m-22000N / m.

[0071] In order to prevent the buffer structure 2 from rotating in a non-load-bearing state, rotating in a low-load-bearing state, rotating in a load-bearing state, and locking in an over-load-bearing state, locking structures 3 are respectively provided at the connection between the upright pole 11 and the base 12.

[0072] The locking structure 3 includes at least one pair of latching members 31 and at least one pair of supporting members 32. The supporting members 32 are U-shaped, and a connecting hole is provided on one side of the supporting members 32. The supporting members 32 are provided at the connection between the vertical pole 11 and the base 12, and one end of the supporting members away from the closure is symmetrically provided on both sides of the connection between the vertical pole and the base.

[0073] The retaining member 31 is a telescopic structure. The retaining member 31 is composed of two steel pipes, one large and one small, which are sleeved together. The end of the smaller steel pipe away from the connection with the larger steel pipe is in a closed state, and the end of the larger steel pipe away from the connection with the smaller steel pipe is a non-retractable end. The non-retractable end of the retaining member 31 is arranged on a side of the support member (32) away from the connecting hole provided on the support member 32, and the non-retractable end of the retaining member 31 is located on a side of the support member 32 close to the connection between the upright pole 11 and the base 12. The connecting hole and the retaining member 31 are arranged on the same axis. A signal receiving module is arranged in the larger steel pipe, and the retaining member 31 is electrically connected to the signal receiving module.

[0074] When the control module transmits an unlocking control signal to the signal receiving module, the locking member 31 contracts to reach the shortest state, and the end of the locking member 31 away from the non-retractable end is disconnected from the connection hole provided on the support member 32;

[0075] When the control module transmits a locking control signal to the signal receiving module, the blocking member 31 is extended to reach the longest state, and the blocking member 31 is connected to the connecting hole provided on the supporting member 32 to block the rotating vertical rod 11 and lock it.

[0076] Preferably, to prevent the locking member 31 from breaking due to excessive rotation force, the locking structure 3 includes at least one pair of brakes 33, and the brakes 33 are arranged at the connection between the vertical rod 11 and the base 12 or at the connection between the vertical rod 11 and the connecting rod 23;

[0077] The brake 33 includes brake calipers symmetrically arranged on both sides of the rotation plane of the vertical pole 11, and brake pads are arranged on the brake calipers. The brake pads are arranged on a side surface of the brake caliper close to the rotation plane of the vertical pole 11, and the brake pads are located close to the connection between the vertical pole 11 and the base 12 or the brake pads are located close to the connection between the vertical pole 11 and the connecting rod 23. The brake 33 is far away from the connection between the vertical pole 11 and the base 12 or the brake 33 is far away from the connection between the vertical pole 11 and the connecting rod 23. The signal receiving module is electrically connected to the brake 33;

[0078] When the control module transmits a locking control signal to the signal receiving module, the brake caliper clamps toward one side of the rotation plane of the vertical pole 11, and the brake pad approaches one side of the connection between the vertical pole 11 and the base 12, and stops clamping after the connection between the vertical pole 11 and the base 12 is fully in contact, and the friction force generated between the brake pad, the connection between the vertical pole 11 and the base 12 locks the rotating connection, preventing the vertical pole 11 from continuing to rotate;

[0079] When the control module transmits an unlocking control signal to the signal receiving module, the brake caliper opens toward the side of the rotation plane away from the upright 11, and stops opening when the brake pad is close to one end of the connection between the upright 11 and the base 12 and the connection between the upright 11 and the base 12 is completely separated, thereby separating the brake pad and the rotation connection between the upright 11 and the base 12, thereby making the connection between the upright 11 and the base 12 rotatable.

[0080] In order to prevent the slider 21 from sliding in a non-load-bearing state, a low-load-bearing state, and a load-bearing state, a pin hole 211 is provided on the slider 21, and a pin shaft 34 is provided on the guide rail 121. The pin shaft 34 is a telescopic structure. The pin shaft 34 has the same structure as the positioning member 31. A signal receiving module is provided in the pin shaft 34. The pin shaft 34 and the signal receiving module are electrically connected. The pin hole 211 provided on the slider 21 and the pin shaft 34 are adapted to each other.

[0081] When the pole double-track safety device is in the non-load-bearing state, low load-bearing state and load-bearing state, the pin hole 211 is extended to the longest, the pin hole 211 and the pin shaft 34 are in a locked state, the pin shaft 34 is in an extended state and the pin shaft 34 is sleeved into the pin hole 211;

[0082] When the double-track safety device of the vertical pole is in an overload-bearing state, the pin hole 211 and the pin shaft 34 are in an unlocked state, the pin hole 211 is tightened to the shortest, the pin shaft 34 is in a tightened state, and the upper end surface of the pin shaft 34 is flush with the lower end surface of the guide rail 121.

[0083] The locking structure 3 also includes a limiting structure 35, and the limiting structure 35 includes:

[0084] A pair of limit blocks 351 are symmetrically arranged on the upper end surface of the base 12 and located between the slider 21 and the adjacent upright pole 11. The side surfaces of the two sliders 21 separated from each other in the non-load-bearing state are respectively in contact with the two limit blocks 351;

[0085] Or a pair of anti-rotation blocks are symmetrically arranged on the separated side surfaces of the two uprights 11, and the separated side surfaces of the two uprights 11 in a non-load-bearing state are respectively in contact with the two anti-rotation blocks.

[0086] In order to improve the detection of the wire rope 131 and prevent the wire rope 131 from breaking during use, and to prevent the wire rope 131 from being damaged due to excessive impulse during the use of the wire rope 131, a control module is provided. The control module includes a control module and a tension detection module, a signal receiving module and an alarm module that are respectively communicated with the control module. The tension detection module is a tension meter 4 and is arranged on the wire rope 131. The tension detection module is used to detect the magnitude of the tension force applied to the wire rope 131. The signal receiving module is arranged in the locking structure 3. The control module sends a corresponding unlocking or locking control signal to the signal receiving module according to the force measurement signal of the tension detection module, and the signal receiving module controls the locking structure 3 to lock or unlock according to the corresponding signal received.

[0087] Calculation method of impulse:

[0088] I = F × △t

[0089] Among them, I represents impulse, F represents force, and △t represents time (Ns).

[0090] Calculation method of force:

[0091] F=m×a

[0092] Among them, F represents force, m represents the mass of the object, and a represents the acceleration of the object.

[0093] In order to prevent the vertical pole 11 from breaking or bending during operation of the device, the angle between the connecting rod 23 and the vertical pole 11 in a non-load-bearing state is 50° to 70°.

[0094] When the angle between the connecting rod 23 and the vertical rod 11 is less than 50° in the non-load-bearing state, the connection between the end of the vertical rod 11 away from the base 12 and the connecting rod 23 is too short, and the connection between the end of the vertical rod 11 close to the base 12 and the connecting rod 23 is too long. The end of the vertical rod 11 close to the base 12 generates a huge torque, which can easily cause the connection between the vertical rod 11 and the base 12 to break directly. In addition, because the connecting rod 23 is too long, the impact reduction effect cannot be achieved as expected.

[0095] When the angle between the connecting rod 23 and the vertical pole 11 is greater than 70° in a non-load-bearing state, the connection between the end of the vertical pole 11 away from the base 12 and the connecting rod 23 is too long, and the connection between the end of the vertical pole 11 close to the base 12 and the connecting rod 23 is too short, which can easily cause the vertical pole 11 to break directly or bend.

[0096] Preferably, in order to reduce the possibility of the vertical pole 11 breaking or bending during operation of the device, the angle between the connecting rod 23 and the vertical pole 11 in a non-load-bearing state is 60°-65°.

[0097] When the steel wire rope 131 is subjected to an impact force, the impact force is transmitted to the vertical pole 11, and then the force is transmitted to the buffer structure 2 through the vertical pole 11, and then the buffer force is reduced by the elastic connector 22 in the buffer structure 2, thereby protecting the steel wire rope and preventing the steel wire rope 131 from breaking.

[0098] A control method for a pole-mounted dual-lane safety device with intelligent reminder, which is applied to any of the above-mentioned pole-mounted dual-lane safety devices with intelligent reminder, comprises the following steps:

[0099] S1. The tension meter 4 obtains the tension of the wire rope 131 or changes in tension and records it as force information and sends it to the control module;

[0100] S2. The control module is provided with four thresholds, namely, over-load state, load state, under-load state and no-load state. The control module receives force information, and sends corresponding control signals to the alarm module and the locking structure 3 according to the force information. The locking structure 3 controls the unlocking or locking of the vertical pole 11 according to the control signal, and the alarm module determines whether to send an alarm signal according to the control signal.

[0101] The maximum bearing tension of the steel wire rope 131 is defined as T max , define the current tension of the wire rope 131 as T 0 , and define when T 0 ≥85%T max It is in overload state, when 85%T max >T 0 >20%T max When it is load-bearing state, 20%T max ≥T 0 ≥5%T max It is in low load-bearing state when T 0 <5%T max S2 is in a non-load-bearing state; S2 specifically includes the following steps:
